Description

  The present invention relates to a toilet device for discharging water stored in a bowl and washing the inside of the bowl.

  A common toilet device is provided with a trap portion at the bottom of a bowl as in Patent Document 1, for example, and seals water, thereby preventing insects, small animals, odors and the like from entering the toilet room from the drainage destination.

  By the way, this kind of toilet device supplies water into the bowl by the water supply means after using the toilet, drains the accumulated water in the bowl, cleans the inner surface of the bowl, and supplies the water immediately after discharging the accumulated water in the bowl. The water is supplied into the bowl by the means, so that the water level of the stored water in the bowl becomes a constant water level and is prepared for the next cleaning of the toilet bowl.

Here, for example, if the water level of the stored water in the bowl is set low, the ability to transport the filth due to the water discharged from the bowl during cleaning is low, and filth adheres to the inner surface of the bowl located above the stored water. For this reason, there is no problem in the case of urine, but in the case of stool, the bowl may not be cleaned cleanly. For this reason, the water level in the bowl has been set high enough to clean the filth cleanly, but in this case, a large amount of water is drained during bowl cleaning even in the case of urination, which wastes water. Resulting in. In the case of urine cleaning, it is conceivable to supply a small amount of water from the water supply means into the bowl and discharge only a part of the water stored in the bowl. Is not hygienic because there is a risk of breeding.

  The present invention has been invented in view of the above-mentioned conventional problems. In the case of urine, the amount of water discharged during washing can be reduced to save water, and in the case of stool, filth is reliably discharged. In order to clean the inside of the bowl and prevent bacteria from growing in the water stored in the bowl, it is possible to replace all the water stored in the bowl with new water at the time of cleaning. An object of the present invention is to provide a toilet device capable of realizing water saving in the case of urine.

  In order to solve the above-mentioned problems, a toilet device according to the present invention discharges the accumulated water in the bowl 1 and supplies water into the bowl 1 by the water supply means 3 to collect the normal level water in the bowl 1. In the apparatus, the water supply means 3 supplies water into the bowl 1 to provide water level changing means for changing the water level of the stored water in the bowl 1 to a high water level higher than the normal water level. To do. By having such a configuration, in the case of urine where the conveyance capacity by drainage at the time of cleaning may be relatively low, the level of the stored water in the bowl 1 is set to the normal water level, and the stored water discharged at the time of cleaning is used. In the case of a stool that can save water by reducing the amount of water and requires the ability to transport wastewater during washing, the water level in the bowl 1 is set to a high water level to reliably discharge filth and clean the bowl 1 Can be washed. Also, in order to prevent germs from remaining in the stored water in the bowl 1 and breeding, all the stored water in the bowl 1 is discharged from the bowl 1 regardless of the level of the stored water in the bowl 1 at the time of washing. Even when set to, all of the water stored in the bowl 1 can be replaced with new water supplied from the water supply means 3 while realizing the above water saving.

  The water level changing means includes a seating detection means 8 for detecting that a person is seated on the toilet seat 2, and when the seating detection means 8 detects that a person is seated on the toilet seat 2, Is preferably supplied with a control means for automatically changing the level of the water stored in the bowl 1 from the normal water level to the high water level. In this case, the control means assumes that when a person is not seated on the toilet seat 2, a man urinates and maintains the water level of the accumulated water in the bowl 1 at the normal water level. When it is detected that a person is seated, the water level in the bowl 1 can be automatically changed to a high water level assuming that the user is convenient, and the water level in the bowl 1 is changed to the usage mode. It can be changed automatically in response.

  The water level changing means is preferably constituted by an operation unit 12 for switching whether or not to supply water into the bowl 1 by the water supply means 3. The water level changing means can be configured with a simple configuration, and the water level of the stored water can be changed by the user.

  Further, the control means supplies water into the bowl 1 by the water supply means 3 when the seating detection means 8 detects that a person has been seated on the toilet seat 2 continuously for a preset time t4. It is preferable that the water level of the stored water is changed to a high water level. Only when it is detected that a person has been seated on the toilet seat 2 for a set time t4, the water level in the bowl 1 can be changed to a high water level. It is possible to prevent the stored water level in the bowl 1 from being changed to a high water level, and the water level in the bowl 1 can be reliably changed to a high water level only when used in the stool.

  The control means supplies water to the bowl 1 by the water supply means 3 when the seating detection means 8 detects that a person is seated on the toilet seat 2 and changes the water level in the bowl 1 from the normal water level to the normal water level. After that, when the person is seated on the toilet seat 2 for the set time t4 after the person is seated on the toilet seat 2, water is supplied into the bowl 1 by the water supply means 3. It is preferable that the water level in the bowl 1 is changed from the middle water level to the high water level higher than the middle water level. In this case, in the case of a female urine that requires a relatively short time, the water level in the bowl 1 is set to a medium water level lower than the normal water level, so that the conveying capacity by drainage at the time of subsequent cleaning is increased compared to the normal water level. As a result, the paper used during the female urination can be reliably discharged out of the bowl 1. Even in the case of this female urine, the water level in the bowl 1 can be reduced to a medium water level lower than the high water level to reduce the amount of water discharged during washing, thereby saving water.

  Moreover, it is preferable that the said water supply means 3 supplies water to the part located above the water level of the stored water in the bowl 1 at least when the normal water level is set to the inner surface of the bowl 1. When the seating detection means 8 detects that a person has been seated on the toilet seat 2 for the set time t4, that is, in the case of male stool or female stool, the level of the accumulated water in the bowl 1 Can be changed to a high water level after the normal water level is changed from the normal water level to the medium water level. When the water level in the bowl 1 is changed from the normal water level to the intermediate water level, the water is supplied into the bowl 1 by the water supply means 3. A portion of the inner surface of the bowl 1 above the accumulated water can be pre-cleaned with water, and this prevents the inner surface of the bowl 1 from being soiled.

  Further, it is preferable to provide a detergent supply device 9 that mixes detergent into the water supplied into the bowl 1 by the water supply means 3 when the water level in the bowl 1 is changed from the normal water level to the middle water level. During the pre-cleaning, the inner surface of the bowl 1 can be cleaned with water containing a detergent.

  In addition, it is preferable to provide a bubble mixing device 10 for mixing bubbles in the water supplied into the bowl 1 by the water supply means 3 when the water level in the bowl 1 is changed from the normal water level to the middle water level. During the pre-cleaning, the inner surface of the bowl 1 can be protected with a foam layer made of water containing air bubbles, and dirt can be further prevented from adhering to the inner surface of the bowl 1 during defecation.

  In the present invention, in the case of urine, it is possible to save water by reducing the amount of stored water discharged at the time of washing, and in the case of stool, the filth can be surely discharged to clean the inside of the bowl cleanly. In order to prevent germs from remaining in the water and propagating, the above water-saving mode can be used when all the stored water in the bowl is discharged from the bowl during cleaning regardless of the water level in the bowl. It is possible to replace all the water stored in the bowl with new water supplied from the water supply means while realizing it.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings. The toilet apparatus of an example of this embodiment shown in FIG. 1 supplies water into the bowl 1, the openable / closable toilet seat 2 disposed on the bowl 1, and the bowl 1, similarly to a general seated flush toilet. A water supply means 3 is provided.

  The water supply means 3 is located above the water level of the stored water on the inner surface of the bowl 1 (more specifically, the level of the stored water at the high water level described later) so that the inner surface of the stored water of the bowl 1 can be cleaned simultaneously with the water supply. What supplies water to the peripheral part of the upper end part to be used is used. Here, as a means for switching whether or not to supply water from the water supply means 3 into the bowl 1, an opening / closing valve 3 b is provided in the flow path 3 a of water supplied into the bowl 1, and the opening / closing valve 3 b is opened. In this case, a constant flow of water is supplied from the water supply means 3 into the bowl 1 so that the inside of the bowl 1 can be cleaned. Specifically, when the on-off valve 3b is opened, 17.5 L / min of water is always supplied into the bowl 1.

  A turn trap 4 that can be turned upside down is provided as a trap portion at the bottom of the bowl 1. The turn trap 4 is formed of a tubular member that can be bent and deformed. One end of the turn trap 4 is connected to a drain port 1 a that protrudes from the bottom of the bowl 1 and the other end is opened in the chute 5. The turn trap 4 drives the motor device 6 so that the discharge port 4a formed of the other end opening which is bent and deformed to the free end is directed upward as shown by the solid line in FIG. 1 and directed downward as shown by the broken line. So that it can be reversed. Accordingly, when the motor device 6 is driven, the turn trap 4 stores the water in the bowl 1 with the discharge port 4a facing up, and the state in which the water in the bowl 1 is discharged with the discharge port 4a facing down. It can be switched.

  As shown in FIG. 2, a motor device 6 that drives the turn trap 4 and an on-off valve 3 b that switches whether or not to supply cleaning water into the bowl 1 are electrically connected to the control unit 7. The control unit 7 is connected with a cleaning operation unit 11 including a switch. By manually operating the cleaning operation unit 11, the control unit 7 controls the on-off valve 3b and the motor device 6 as shown below. Thus, the inside of the bowl 1 can be cleaned.

  That is, when the on-off valve 3b is closed and the discharge port 4a of the turn trap 4 is facing upward (that is, in a state where accumulated water is accumulated in the bowl 1), the control unit 7 operates the cleaning operation unit 11. 3-5, the on-off valve 3b is opened to start supplying water into the bowl 1 by the water supply means 3, and at the same time, the water in the bowl 1 is discharged with the discharge port 4a of the turn trap 4 facing downward. To start. Next, a predetermined time t1 elapses after the control unit 7 starts discharging the water from the bowl 1 with the discharge port 4a of the turn trap 4 facing downward (that is, when the on-off valve 3b is opened). At this time, the discharge of the water in the bowl 1 is stopped with the discharge port 4a of the turn trap 4 facing upward. Thus, all of the water stored in the bowl 1 together with the water supplied into the bowl 1 by the water supply means 3 is discharged through the drain port 1a, the turn trap 4 and the outlet 5a of the chute 5 in this order. It will be. After that, when the predetermined time t2 (t2> t1) elapses from when the on-off valve 3b is opened, the on-off valve 3b in the open state is closed and water is supplied into the bowl 1 by the water supply means 3. Stop supplying. As a result, after the time when the drainage is stopped, the water supplied into the bowl 1 by the water supply means 3 is not drained but is gradually accumulated in the turn trap 4 and the bowl 1, and the water supply is stopped. At that time, the water level in the bowl 1 is always the normal water level indicated by the solid line a in FIG. Specifically, when 5 seconds have passed since the discharge port 4a of the turn trap 4 is turned downward, the discharge port 4a of the turn trap 4 is turned upward, and when 5 seconds have passed (that is, when the on-off valve 3b is opened) The valve 3b is closed at the time when 10 seconds have elapsed since then, and then an amount of 1.46 L of water is supplied into the bowl 1 to reach the normal water level. As a result, the amount of water stored in the bowl 1 to the normal water level is 1.46L.

  The normal water level is set to be considerably lower than the maximum water level determined by the height of the discharge port 4a of the turn trap 4 turned upward, but is located above the drain port 1a of the bowl 1, As a result, the turn trap 4 is sealed in a state where the water is stored in the bowl 1 thereafter, and insects, small animals, odors and the like are prevented from entering the toilet room from the drainage destination.

  Here, the toilet apparatus of the present invention is provided with a water level changing means for changing the level of the stored water in the bowl 1 to the high water level shown by the broken line b in FIG. 1 higher than the normal water level. As the changing means, seating detection means 8 for detecting that a person is seated on the toilet seat 2, and when the seating detection means 8 detects that a person is seated on the toilet seat 2, water is automatically supplied into the bowl 1 by the water supply means 3. And a control means for changing the water level of the stored water in the bowl 1 from the normal water level to the high water level.

  As the seating detection means 8, a seating detection sensor capable of always detecting whether or not a person is seated on a conventionally known toilet seat 2, such as a pressure sensor provided on the toilet seat 2, a touch sensor, an infrared sensor or the like. Is used.

  The control means is constituted by a control unit 7 to which the seating detection means 8 is connected. As shown in FIGS. 3 to 5, the control unit 7 closes the on-off valve 3 b and keeps the discharge port 4 a of the turn trap 4 upward until the seating detection means 8 detects that a person is seated on the toilet seat 2. To do. 4 and 5, when the seating detecting means 8 detects that a person is seated on the toilet seat 2, the controller 7 first opens the on-off valve 3b for a certain time t3 at this time, thereby 1, a predetermined amount of water is supplied, and the water level of the stored water in the bowl 1 is changed from the normal water level to the middle water level shown by the broken line C in FIG. Specifically, when seating is detected by the seating detection means 8 when the accumulated water is at a normal water level, the opening / closing valve 3b is opened for 5 seconds, and 1.46 L of water is supplied into the bowl 1 for a total of 2.92 L. Accumulate the accumulated water to the middle water level.

  Then, when it is detected by the seating detection means 8 that a person has been seated on the toilet seat 2 for a preset time t4 after the seating detection means 8 has been seated, as shown in FIG. From this time, the on-off valve 3b is opened for a predetermined time t5 (in the embodiment, t5 = t3), whereby a predetermined amount of water is supplied into the bowl 1 and the water level in the bowl 1 is increased from the middle water level. Change to water level. Specifically, when it is detected that a person has been seated on the toilet seat 2 continuously for 30 seconds, the on-off valve 3b is opened for 5 seconds and 1.46 L of water is supplied into the bowl 1 for a total of 4.38 L. Accumulate the accumulated water to raise the water level.

  With the above control, water can be supplied and drained into the bowl 1 as shown in FIG. 3 for male urine, FIG. 4 for female urine, and FIG. 5 for male and female urine.

  That is, in the case of male urine shown in FIG. 3, since the seating detection means 8 does not normally detect that a person is seated on the toilet seat 2, the controller 7 does not supply water into the bowl 1 by the water supply means 3 before washing. Accordingly, when the man pisses and the cleaning operation unit 11 is operated (that is, the time indicated by X in FIG. 3), the water level of the stored water is about the normal water level. The amount of water discharged to the outside of the bowl 1 by the above operation was supplied into the bowl 1 while the amount 1.46L of the water stored up to the normal water level and the discharge port 4a of the turn trap 4 faced downward. The combined amount of water 1.46L is 2.92L. As a result, only a small amount of water is drained out of the bowl 1 during male urination, thus saving water. Moreover, since all of the water stored in the bowl 1 can be drained and replaced during cleaning by the operation of the cleaning operation unit 11, it is possible to prevent bacteria from growing in the bowl 1.

  In the case of the female urine shown in FIG. 4, it is usually detected by the seating detection means 8 that a person has been seated on the toilet seat 2, and then the seating is detected before the set time t4 elapses. Therefore, the control unit 7 supplies water into the bowl 1 by the water supply means 3 when a person is seated on the toilet seat 2 and sets the level of the stored water at the normal water level to the middle water level. Do not supply water. In this case, since the level of the stored water is about the middle water level when the woman urinates and the cleaning operation unit 11 is operated (that is, the time indicated by Y in FIG. 4), the cleaning operation unit 11 The amount of water discharged out of the bowl 1 by one operation is supplied to the bowl 1 while the amount of retained water 2.92L accumulated to the middle water level and the discharge port 4a of the turn trap 4 are directed downward. The total amount of water produced is 1.38L, which is 4.38L. Here, normally, after the woman has pissed, the used paper is put into the bowl 1, but in this example, the water level after the woman has pissed is higher than the normal water level as described above. Since the water level becomes higher by one step, the conveying capacity by the waste water at the time of washing performed by the operation of the washing operation unit 11 can be increased as compared with the normal water level, and this is put into the bowl 1 at the time of female urination. The paper can be reliably discharged out of the bowl 1. In addition, even in the case of female urination, only a small amount of accumulated water is discharged out of the bowl 1 compared to the time of stool described later, so that water can be saved.

  Further, in the case of male stool and female stool shown in FIG. 5, it is detected by the normal seating detection means 8 that a person is seated on the toilet seat 2, and thereafter, after the seating on the toilet seat 2, the set time t4 continues to the toilet seat 2. It is detected that a person is seated. Therefore, when the controller 7 is seated, the water supply means 3 supplies water into the bowl 1 to set the level of the stored water at the normal water level to the middle water level. Thereafter, when the set time t4 has elapsed, the water supply means 3 further supplies the bowl 1 with the water level. Water is supplied inside and the water level at the middle water level is set to the high water level. In this case, since the water level in the bowl 1 is about a high water level when the man or woman stools and the cleaning operation unit 11 is operated (that is, the time indicated by Y in FIG. 5), The amount of water discharged to the outside of the bowl 1 by one operation of the operation unit 11 is 4.38 L of water stored up to a high water level while the discharge port 4a of the turn trap 4 is facing downward. The total amount of water supplied in 1 is 1.84L, which is 5.84L. As a result, in the case of male stool and female stool, the ability to transport filth when drained by the operation of the washing operation unit 11 can be increased as compared with the normal water level and the middle water level, and the filth is removed from the bowl 1 Can be discharged reliably. Further, in this case, since the stored water is at a high water level, dirt is hardly attached to the inner surface of the bowl 1, and the inside of the bowl 1 can be cleaned cleanly. Further, when the seating detection means 8 detects that a person is seated on the toilet seat 2, the water supplied to the bowl 1 by the water supply means 3 (that is, the water supplied to the bowl 1 to make the accumulated water the middle water level). Since the water flows along the inner surface of the bowl 1 above the stored water and is stored in the bowl 1, the inner surface of the bowl 1 can be pre-cleaned (pre-cleaned) with water supplied from the water supply means 3, thereby It is possible to further prevent filth from adhering to the inner surface of the bowl 1.

  In the toilet apparatus in the above embodiment, the detergent supply device 9 for mixing detergent into the water supplied into the bowl 1 by the water supply means 3 when the water level in the bowl 1 is changed from the normal water level to the middle water level is provided. It may be provided. The detergent supply device 9 supplies the detergent to the water (that is, water used for pre-cleaning in FIGS. 4 and 5) supplied into the bowl 1 by the water supply means 3 when the level of the stored water is changed from the normal water level to the middle water level. For example, as shown in FIG. 6, one that is connected in the middle of the flow path 3 a constituting the water supply means 3 and supplies detergent to the water flowing through the flow path 3 a is used. Moreover, as the detergent supplied by the detergent supply device 9, for example, a stock solution of a general household detergent used by diluting with water to 1000 times to 50000 times is used, and the detergent supply device 9 has an arbitrary dilution factor. Thus, the water used for the pre-cleaning is automatically supplied. Thereby, the antifouling effect on the inner surface of the bowl 1 can be efficiently enhanced with a small amount of detergent, and the inner surface of the bowl 1 can be effectively cleaned when drained water is discharged later. The detergent supply device 9 supplies the water supplied into the bowl 1 by the water supply means 3 when the water level of the stored water is changed from the normal water level to the middle water level (that is, water used for pre-cleaning in FIGS. 4 and 5). Only the detergent may be supplied, or the detergent may also be supplied to the water supplied into the bowl 1 by other water supply means 3.

  Further, in the toilet apparatus in the above embodiment, the bubble mixing device 10 for mixing bubbles in the water supplied into the bowl 1 by the water supply means 3 when the water level in the bowl 1 is changed from the normal water level to the middle water level. It may be provided. As the bubble mixing device 10, for example, as shown in FIG. 6, outside air that is provided in the middle of the flow path 3 a constituting the water supply means 3 and uses the ejector effect at the time of water supply as bubbles in the flowing water in the flow path 3 a. What is mixed in is used. Thereby, the inner surface of the bowl 1 can be protected with a foam layer made of water containing bubbles, and the adherence of filth during defecation can be reduced. In the case where both the bubble mixing device 10 and the detergent supply device 9 are provided as shown in FIG. 6, the apparent volume of the cleaning liquid is increased by mixing bubbles in the water mixed with the detergent, and the bowl 1 Since the cleaning liquid spreads widely on the inner surface of the surface, the antifouling effect by the cleaning liquid can be further enhanced. The bubble mixing device 10 is used for pre-cleaning in FIG. 4 and FIG. 5 when water is supplied into the bowl 1 by the water supply means 3 when the water level in the bowl 1 is changed from the normal water level to the middle water level. The water may be supplied only to the water), or the detergent supplied to the water supplied into the bowl 1 by other water supply means 3 may be used. In FIG. 6, both the bubble mixing device 10 and the detergent supply device 9 are provided, but only one of them may be provided.

  Further, when the person is seated on the toilet seat 2 by the seating detection means 8, the control means supplies water into the bowl 1 by the water supply means 3 and changes the water level in the bowl 1 from the normal water level to the middle water level. Thereafter, when the seating detection means 8 detects that a person has been seated on the toilet seat 2 for a set time t4, water is supplied into the bowl 1 by the water supply means 3, and the water level in the bowl 1 is adjusted. In other words, the water level in the bowl 1 is gradually increased from the normal water level to the high water level based on the detection result of the seating detection means 8. However, until the set time t4 elapses from when the person is seated on the toilet seat 2 by the seating detection means 8, water is not supplied from the water supply means 3 into the bowl 1 and the water level is changed to the normal water level without changing. Thereafter, the toilet seat is detected by the seating detection means 8. By supplying water into the bowl 1 may be changed the water level of accumulated water in the bowl 1 from the normal water level to the high level at the time the person has passed the set time t4 from the time of sitting on.

  Furthermore, you may provide the operation part 12 which operates the water supply means 3 as said water level change means. Specifically, as shown in FIG. 7, a stool switch 12a and a female urine switch 12b are provided as the operation unit 12 in the vicinity of the washing operation unit 11 including switches. When the female urine switch 12b is manually operated, the control unit 7 opens the on-off valve 3b at this point in time for a predetermined time t3 at the same time as in the above-described embodiment. A predetermined amount of water is supplied to change the water level in the bowl 1 from the normal water level to the middle water level. Further, when the stool switch 12a is manually operated, the control unit 7 at this time makes the on / off valve 3b longer than the time t3 when the on / off valve 3b is opened when the female urine switch 12b is operated. It is opened for a certain period of time, whereby a predetermined amount of water is supplied into the bowl 1 and the water level in the bowl 1 is changed from the normal water level to the high water level.

  In this way, the water level changing means can be configured by the operation unit for operating the water supply means 3, and in this case, the bowl 1 corresponds to three types of usage forms of male urine, female urine, male urine and female stool. You can change the water level inside.

  In any of the above-described embodiments, the toilet apparatus is cleaned by a turn trap type. However, a siphon type trap is provided as a trap part to drain water in the bowl 1 by siphon action, or it is washed off. It can also be a formula.
